I have not bought fabric that was 44-45 in a long time. Seems most is 40-42 now. I do have some fabric from the 70s that is 44-45" wide. I rarely use patterns, but have needed to make adjustments for a few that were figured for wider fabric and I could not get the required subcuts out of what they said. At least I was using stash, so had more than the pattern listed.
